Your schoolteachers probably told you most species wouldn’t (or maybe couldn’t)successfully interbreed with one another. If some did, their hybrid offspring, like mules, couldn’t have babies of their own. That explanation was a bit oversimplified.

Two of the most destructive species of invasive termites are joining forces in Florida. By mating together, they're forming prolific hybrid colonies. Scientists are now worried about the potential damage these insects will inflict on Florida's dwellings. »3/26/15 7:40am 3/26/15 7:40am

The Cuban Crocodile is a critically endangered species. What's threatening it? A history of hunting, habitat destruction, and, increasingly, the rise of a new group of crocodile hybrids, resulting from interbreeding with another crocodile species. The full story is after the jump.»8/04/14 2:48pm 8/04/14 2:48pm

This single (and quite colorfully blossoming) tree grows 40 different varieties of peaches, plums, apricots, nectarines, cherries, and even almonds — but just how does it do it? »7/22/14 9:45am 7/22/14 9:45am

In today's comments, we envied the polite small-talk abilities of the marmoset, looked up at the heavens with a mixture of awe and suspicion, and learned one more reason to fear the deep: hybrid sharks. »10/17/13 4:30pm 10/17/13 4:30pm

Underneath our skin all people are the same — unless, that is, you have tentacles instead of legs, a fishtail where your waist ends, or a long, elegant beak springing from your face. »10/08/11 9:30am 10/08/11 9:30am

Enrique Gomez De Molina builds impossible hybrid creatures out of fur and beaks and feathers. They imagine a distant universe where animals are at once avian and mammal, and live side by side with intelligent insect tribes. »4/23/11 9:00am 4/23/11 9:00am
